The paper "Towards a Methodology for Building Ontologies" by Mike Uschold and Martin King outlines a comprehensive methodology for constructing ontologies, emphasizing the ontology capture phase. The authors review existing literature and share their experiences in developing a significant ontology. They propose a skeletal methodology with stages such as identifying the purpose, capturing the ontology, coding, integrating existing ontologies, and evaluating and documenting the final product. Key points include: 1. **Purpose**: Clearly defining the intended use and users of the ontology. 2. **Capture**: Identifying key concepts and relationships, producing precise definitions, and agreeing on terms. 3. **Coding**: Representing the conceptualization in a formal language, choosing a meta-ontology, and creating the code. 4. **Integration**: Using existing ontologies and addressing challenges in achieving shared understanding. 5. **Evaluation**: Assessing the ontologies and their associated software environment. 6. **Documentation**: Establishing guidelines for documenting ontologies. The authors also describe a case study where they used a middle-out approach to define basic concepts before more abstract ones, which they found effective in reducing rework. They recommend separating the capture and coding phases to avoid being influenced by accidental features of formalism and suggest defining cognitively basic terms first to enhance clarity and reduce ambiguity.The paper "Towards a Methodology for Building Ontologies" by Mike Uschold and Martin King outlines a comprehensive methodology for constructing ontologies, emphasizing the ontology capture phase.
